The type of photography that you are planning to use is an important decision factor. Here we have evaluated the Canon EF 50mm f/1.8 STM and the Sigma 35mm F1.4 DG HSM for their suitability to various photography scenarios:
Size and Weight Comparison The size of a lens is a crucial factor to consider when comparing two lenses. Sigma 35mm F1.4 DG HSM is the longer of the two lenses at 94mm. The Canon EF 50mm f/1.8 STM with a length of 39mm, is 55mm shorter. Besides being longer, the Sigma 35mm F1.4 DG HSM also has a larger diameter of 77mm compared to the Canon EF 50mm f/1.8 STM's 69mm diameter.
Below you can find a scaled side-by-side image of Canon EF 50mm f/1.8 STM and Sigma 35mm F1.4 DG HSM to get a better idea of how their sizes compare in real life.
Comparison image of the Canon EF 50mm f/1.8 STM and the Sigma 35mm F1.4 DG HSM Size and Weight The weight of a lens is equally significant as its external dimensions, particularly if you intend to handhold your camera and lens combination for extended periods. Canon EF 50mm f/1.8 STM weighs 159g, which means it is 506g (76%) lighter than the Sigma 35mm F1.4 DG HSM which has a weight of 665g.
Filter Threads
The Canon EF 50mm f/1.8 STM has a filter size of 49mm whereas the Sigma 35mm F1.4 DG HSM has a 67mm diameter. Larger filters are generally more expensive than the smaller ones given all the other features are equal.
Below are links to the 49mm filters that we recommend you to consider for the Canon EF 50mm f/1.8 STM:
And these are the 67mm filters that we recommend for the Sigma 35mm F1.4 DG HSM:
Lens Mounts
Both the Canon EF 50mm f/1.8 STM and the Sigma 35mm F1.4 DG HSM has the same Canon EF lens mount . Some of the latest released cameras that are compatible with the Canon EF lenses are Blackmagic URSA 12K LF , Z CAM E2-F6 II 6K and Z CAM E2-S6 II 6K .
Pentax KAF3 , Sony Alpha , Sigma SA , Nikon F (FX) and Leica L mounts.
Focal Range
Canon EF 50mm f/1.8 STM is a prime lens with fixed focal lenght of 50mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of
80mm .
On the other hand, the Sigma 35mm F1.4 DG HSM is a prime lens with fixed focal lenght of 35mm. When it is mounted on an APS-C sensor camera with 1.6x crop, it provides a 35mm (FF) equivalent of 56mm .
